Tile chart

The chart displays a matrix.
The colour of the tile represents the value at each
intersection.

The chart is constructed from
a combination of Bar, Column and XY-Scatter. The Bar and Column
chart are used to provide category axis labels. The tiles are
derived from the XY-scatter chart.The chart uses data from
conditional formula in order to display a single tile in each
position.

The
workbook contains a step by step explanation on how to
construct the chart.
